1 Claim.

manufacture of shoes and particularly to a type employing an insole for providing a rise or elevation in a portion of the shoe sole as for the inside 5 ball of the foot. It heretofore has been the practice in elevating a portion of the sole of a shoe to insert a wedge-shaped piece of material in the shoe attached to the inner surface of the insole bearing against the foot causing considerable A wedge or insert is also placed between the sole and welting, giving the shoe a bulky appearance and destroying the bottom plane of the outer sole, inclining the shoe instead of offering an inclined support for the foot.

In the present method a rise or wedge is definitely incorporated in the insole organization by including a wedge-shaped piece of material or bevelled leather skiving to the bottom or underside of the insole preferably vulcanized or adhesively secured along the margin of the inner side and fore part thereof, giving an increased thickness to such portion and a rise or elevating support to that portion of the foot of the wearer of the shoe bearing thereon. The insole or wedge piece may be channelled as a unit for preparing an inseam lip .or the parts can be individually channelled before securing together whereupon the process of making the insole and securing the same to the upper and in finishing the shoe can be carried on according to any prevailing practice.

It is therefore an object of the invention to provide a shoe sole with a wedge or elevated portion incorporated unitarily with the insole.

Another object of the invention is to provide an insole with a wedge piece for giving an elevating support to a portion of the foot along a margin of the insole and the wedge applied to the insole so as to lie intermediate of the insole and I1 0 outer sole and form a permanent built-in component of the insole.

Other features of the invention relate to specific details of construction and methods of making the insole to provide a wedge or rise for a portion ...4. of the foot and which will give increased durability to the shoe and comfort to the foot and will not in any wise detract from the style or appearance of the shoe, all of which will be more fully set forth in a description of the accompanying 1 .9 drawing, in which:

$5.5 wedge section of insole material secured tothe This invention relates to improvements in the underside of the insole or upper side as shown in said figure on the inner side of the ball portion thereof to increase the thickness or elevate such "portion with, the insole and wedge section as a unit channelled in the ordinary manner preparatory to forming the inseam lip which extends from the heel breast line around the outline of the shoe.

Figure 2 is a view similar to Figure 1 with the flaps formed by channelling turned up at an 7 angle to provide a lip to which the upper and welt are stitched and illustrating a marginal line of stitching along the outer margin of the wedge section adjacent the base of the outstanding lip.

Figure 3 is a cross section of a shoe taken in relation to the insole along line 3-3, Figure 2.

Figure 4 is a perspective view of the wedge piece or section.

Referring to the drawing, 1 indicates a conventional insole blank, preferably of leather material, cut to an appropriate pattern outline for a definite size and style of shoe. The underside of the blank, which is shown as the upper side in Figures 1 and 2, along the margin of the inner fore part thereof has a wedge or bevel-shaped section 2 preferably of leather material or of the stock of the blank 1, adhesively secured or vulcanized thereon.

The parts as a unit are channelled in the usual manner to provide a pair of flaps 3, i, to be turned up at an angle to the plane of the blank and form a lip 5 to which the upper and welt of a shoe are stitched in the usual manner.

The blank 1 and welt section 2 if preferred may be separately channelled preliminary to se- 190 curing the same together. After the flaps have been turned up to form the lip 5, the wedge section and blank are stitched together by a line of stitching 6 marginally along the outline of the parts and close to the base or root of the lip. The underside of the insole, that is, the blank 1 and wedge section 2, within the lip, is covered with a canvas 01' duck material 7 with the margins thereof lapping the inner side of the lip to reinforce the same representing a common practice in the manufacture of insoles.

Positioning the wedge section between the insole and outer sole provides an increased thickness of inner sole for the area of the wedge section thereby embedded within the sole of the shoe without raising the bottom plane of the outer sole, nor giving the same a bulky appearance. It provides for a normal thickness of insole as a layer above the wedge section presenting a smooth face side for the inner side of the shoe eliminating the use of a full sock lining for the 7 shoe, thereby effecting quite a saving.

Permanently incorporating the wedge in the insole and stitching the same to the upper as well as to the margin of the blank on which the wedge section extends makes it absolutely proof against release when the shoe is worn. It is. principally effective when the foot under weight bears upon the sole and does not come in contact with the foot or cause discomfort to the foot "as commonly occurs when the wedge, is applied or inserted upon the upper face side of the insole; nor

does it cramp the foot within the upper, nor can it distort the shape of the shoe in lasting the upper to the inner sole. l g

In stitching for securing the Wedge section to the blank along the line outside of the inseam lip, it is beyond possible contact with the foot,

for a portion of the ball of the foot, said section having an edge in registry with a corresponding edge of the main layer, and said main layer and skiving section as a unit marginally channelled and formed with a continuous outstanding lip, said layer and section stitched together along and at the outer side of the lip.
